TanStack Router How-To Guides Testing Plan

This plan outlines systematic testing for each how-to guide to verify:

• ✅ Type Accuracy: No TypeScript errors
• ✅ Conceptual Accuracy: Instructions work as described
• ✅ Runtime Accuracy: Applications run without errors
• ✅ Completeness: All necessary steps included

Testing Methodology

Each test will use agent-friendly static analysis rather than running full projects:

1. API Validation: Cross-reference code examples with actual TanStack Router source code
2. Import/Export Verification: Check that all imports exist in the specified packages
3. TypeScript Syntax Check: Validate code patterns against current TypeScript standards
4. Documentation Consistency: Ensure examples match the current API documentation
5. Dependency Verification: Check package.json compatibility and version requirements
6. Code Pattern Analysis: Verify examples follow current best practices and conventions

Execution Plan

1. Phase 1: Basic setup guides (install, environment, deployment)
2. Phase 2: Core functionality (SSR, migration, authentication)
3. Phase 3: Testing and debugging guides
4. Phase 4: UI library integrations

For each guide:

1. Create isolated test environment
2. Follow guide step-by-step
3. Document all findings
4. Update checkbox when complete
5. Move to next guide

If stuck on a guide after multiple attempts:

• Document the blocking issues
• Note what was attempted
• Mark as "needs investigation"
